    摘要: Calibrating a transmit diversity device includes establishing diversity parameter values of diversity parameters for a plurality of signals, where each signal is transmitted from a channel of the transmit diversity device. The following are performed for each diversity parameter value to yield associations: determining a modification parameter value that yields a diversity parameter value, where a modification parameter value describes modulation of a feature of at least one signal; and associating the modification parameter value with the diversity parameter value to yield an association. Calibration data is generated in accordance with the associations.

    摘要: Calculating a phase adjustment includes establishing a current phase adjustment for a signal transmitted from a modifying communication device to a feedback communication device. A control signal is received. The control signal comprises windows communicating power indicators that reflect the power of the signal. A previous window communicates power indicators reflecting the power of the signal, and a current window communicates current power indicators reflecting the power of the signal. A previous power trend is estimated from previous power indicators, and a current power trend is estimated from current power indicators. A power trend change is determined from the previous power trend and the current power trend, and a phase increment is determined in accordance with the power trend change. A next phase adjustment is calculated from the current phase adjustment and the phase increment.

    摘要: A method and system for improving closed loop feedback in transmit diversity communication. In one embodiment of the invention, a predetermined variation of one or more transmit diversity parameters is performed at the transmit diversity transmitter. The receiver compares the transmit diversity parameter values of the received signals to the predetermined variation and transmits to the transmitter a value of a transmit diversity correction parameter. The transmitter may use this correction value to modify the transmit diversity parameter in a subsequent transmission.
